TLDR
The results suggest that climate change has already affected global food production and has likely led to ~1% average reduction in consumable food calories in these ten crops.Abstract:
Crop yields are projected to decrease under future climate conditions, and recent research suggests that yields have already been impacted. However, current impacts on a diversity of crops subnationally and implications for food security remains unclear. Here, we constructed linear regression relationships using weather and reported crop data to assess the potential impact of observed climate change on the yields of the top ten global crops-barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat at ~20,000 political units. We find that the impact of global climate change on yields of different crops from climate trends ranged from -13.4% (oil palm) to 3.5% (soybean). Our results show that impacts are mostly negative in Europe, Southern Africa and Australia but generally positive in Latin America. Impacts in Asia and Northern and Central America are mixed. This has likely led to ~1% average reduction (-3.5 X 1013 kcal/year) in consumable food calories in these ten crops. In nearly half of food insecure countries, estimated caloric availability decreased. Our results suggest that climate change has already affected global food production.read more

TL;DR: In this paper, the authors have discussed the sophisticated adaptation mechanisms and regularity network that improves the water stress tolerance and adaptation in plants, including growth pattern and structural dynamics, reduction in transpiration loss through altering stomatal conductance and distribution, leaf rolling, root-to-shoot ratio dynamics, root length increment, accumulation of compatible solutes, enhancement of transpiration efficiency, osmotic and hormonal regulation, and delayed senescence.

Impact of Climate Change on Agriculture and Its Mitigation Strategies: A Review
TL;DR: This article reviewed the information collected through the literature regarding the issue of climate change, its possible causes, its projection in the near future, its impact on the agriculture sector as an influence on physiological and metabolic activities of plants, and its potential and reported implications for growth and plant productivity, pest infestation, and mitigation strategies and their economic impact.

Climate-Driven Crop Yield and Yield Variability and Climate Change Impacts on the U.S. Great Plains Agricultural Production.
Meetpal S. Kukal,Suat Irmak +1 more
TL;DR: Climate impacts on maize, sorghum, and soybean yields and effect of irrigation for individual counties in this region by employing extensive crop yield and climate datasets from 1968–2013 can serve as an assessment guide for planners, managers, and policy- and decision makers to prioritize agricultural resilience efforts and resource allocation or re-allocation in the regions that exhibit risk from climate variability.

TL;DR: This article reported new twenty-first-century projections using ensembles of latest-generation crop and climate models, which suggest markedly more pessimistic yield responses for maize, soybean and rice compared to the original ensemble.

Climate adaptation by crop migration.

TL;DR: The results suggest that the most damaging impacts of warming on rainfed maize, wheat, and rice have been substantially moderated by the migration of these crops over time and the expansion of irrigation, finding a global migration away from warming climates.

Global food demand and the sustainable intensification of agriculture
TL;DR: Per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960 and forecasts a 100–110% increase in global crop demand from 2005 to 2050.
